Set up Cypress

[jensren]

Later in the project, we will need Cypress tests for end-to-end testing.

Current State

• No Cypress tests are set up
• We do not have anyone on the team who knows a lot about Cypress

Goals for this Epic

• ZenHub board has a 'Ready for Testing' state. This is for after the PR has unit tests, passes all unit tests, and is merged to main. Additionally, this should be reserved for features that are stable and unlikely to be changed significantly
• Cypress is installed and Cypress tests have been added for existing components in 'Ready for Testing'
• Writing Cypress tests for future 'Ready for Testing' components is given priority, so tests are not backlogged
• Team has at least one dedicated tester who knows how to set up Cypress tests
• Highly active front end devs are encouraged to learn Cypress and write their own Cypress tests
